Code Name Viper - NES Gameplay

Gameplay in action


The gameplay has been noted for being similar to Namco's Rolling Thunder. There are two floor levels to switch between, doors that the player must go into to get weapons and items, but there are some differences.

There are also people to be rescued. One of these hostages is a soldier who the player must rescue on every single level (except the last) in order to advance to the next level. The player may also expand the character's life meter, and there are some more obstacles in the game like springs.


  • Commander Jones - was the leader of Ken Smith's Special Missions. People who played the game for the first time are supposed to assume that Jones was just Smith's commanding officer sending him to take down a drug ring that tried to conquer the world.


Ken Smith is a special agent. Commander Jones sends him to South America to take down a drug cartel and rescue kidnapped hostages.

At the end of the game, Smith finds out that Commander Jones was behind the whole thing, and engages him in a fight to the death and as a result, Jones lost his life. While the underground drug routes where Jones was involved were destroyed by Smith, the syndicate he ran was not defeated.


This game lacks a credits sequence for the game's staff. Music composition is confirmed to be done in some capacity by Yoko Shimomura through her official website, though her worklist lists the title as one where her role was merely supportive. Aside from this one other credit is known: the first stage theme was done by Junko Tamiya, confirmed via interview.
